Scaevola plant named ‘Bonsca 1430’

ABSTRACT

A new and distinct cultivar of  Scaevola  plant named ‘Bonsca 1430’, characterized by its compact and spreading plant habit; freely branching habit; early and freely flowering habit; long flowering period; deep violet-colored flowers; and good container and garden performance.

Botanical designation: Scaevola aemula.

Cultivar denomination: ‘BONSCA 1430’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Scaevolaplant, botanically known as Scaevola aemula and hereinafter referred toby the name ‘Bonsca 1430’.

The new Scaevola plant is a product of a planned breeding programconducted by the Inventors in Yellow Rock, New South Wales, Australia.The objective of the breeding program is to create new compact,spreading and early-flowering Scaevola plants with numerous attractiveflowers.

The new Scaevola plant originated from an open-pollination in YellowRock, New South Wales, Australia in March, 2013 of a proprietaryselection of Scaevola aemula identified by the code number 13-12, notpatented, as the female, or seed, parent with an unknown proprietaryselection of Scaevola aemula, as the male, or pollen, parent. The newScaevola plant was discovered and selected by the Inventors as a singleflowering plant from within the progeny of the stated open-pollinationin a controlled greenhouse environment in Yellow Rock, New South Wales,Australia on Mar. 4, 2014.

Asexual reproduction of the new Scaevola plant by vegetative tipcuttings in a controlled greenhouse environment in Yellow Rock, NewSouth Wales, Australia since March, 2014 has shown that the uniquefeatures of this new Scaevola plant are stable and reproduced true totype in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Scaevola have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Bonsca 1430’. These characteristics incombination distinguish ‘Bonsca 1430’ as a new and distinct Scaevolaplant:

-   -   1. Compact and spreading plant habit.    -   2. Freely branching habit.    -   3. Early and freely flowering habit.    -   4. Long flowering period.    -   5. Deep violet-colored flowers.    -   6. Good container and garden performance.

Plants of the new Scaevola can be compared to plants of the femaleparent selection. Plants of the new Scaevola differ primarily fromplants of the female parent selection in flowering habit as plants ofthe new Scaevola are more freely flowering than plants of the femaleparent selection.

Plants of the new Scaevola can be compared to plants of the Scaevolaaemula ‘Wesscaetob’, disclosed in U.S. Plant Pat. No. 19,658. Inside-by-side comparisons, plants of the new Scaevola differ from plantsof the ‘Wesscaetob’ in the following characteristics:

-   -   1. Plants of the new Scaevola are more spreading than and not as        mounding as plants of ‘Wesscaetob’.    -   2. Plants of the new Scaevola flower earlier than plants of        ‘Wesscaetob’.    -   3. Plants of the new Scaevola and ‘Wesscaetob’ differ in flower        petal color as plants of ‘Wesscaetob’ have violet blue-colored        flower petals.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearanceof the new Scaevola plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotographs may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Scaevola plant.

The photograph at the top of the sheet comprises a side perspective viewof a typical flowering plant of ‘Bonsca 1430’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of atypical flowering plant of ‘Bonsca 1430’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurementsand values describe plants grown during the late summer in 20-cmcontainers in an outdoor nursery in Higashiomi, Shiga, Japan and undercultural practices typical of commercial Scaevola production. During theproduction of the plants, day temperatures ranged from 15° C. to 30° C.and night temperatures ranged from 13° C. to 25° C. Plants were threemonths old when the photographs and the detailed description were taken.In the following description, color references are made to The RoyalHorticultural Society Colour Chart, 2007 Edition, except where generalterms of ordinary dictionary significance are used.
